Keflex is a broad-spectrum cephalosporin antibiotic used to treat upper respiratory infections, urinary tract infections, as well as ear, bone, and skin infections. This antibiotic exhibits bactericidal properties by interfering with formation of the cell wall, causing osmotic imbalance and ultimately cell lysis. Sulfa drugs, also known as sulfonamides, are chemical compounds that contain a SO2NH2 moiety. Based on their chemical structure, these drugs are divided into three classes, however, they all have the same mechanism of action. These drugs inhibit bacterial growth by acting as a competitive inhibitor to the enzyme, p-aminobenzoic acid. PABA is required for the biosynthesis of folic acid, which in turn is required for the synthesis of nucleic acids, and ultimately, DNA and RNA. Bacterial organisms sensitive to sulfa drugs are unable to synthesize folic acid in the presence of these antibiotics, and thus are unable to synthesize the compounds necessary for cellular growth and multiplication. prednisone given to dogs The buildup of thick, sticky mucus in the lungs makes people with cystic fibrosis more likely to develop bacterial infections that can last for short periods of time (known as acute infections or exacerbations) or for many years. The good news is that many of these infections can be treated. To keep them in check, antibiotics are taken by people with CF as part of regular daily treatment. For lung exacerbations, people with CF may receive intravenous (IV) -- that is, directly into the veins -- antibiotics in addition to the inhaled or oral antibiotics. See how inhaled antibiotics work to help control bacteria in your lungs. Inhaled antibiotics should be taken last, after bronchodilators (if you take them), mucus thinners, and airway clearance techniques, so your lungs will be as clear of mucus as possible. This allows the antibiotics to reach deep into your lungs to treat the bacteria that cause infection.

Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs. The original antibacterial sulfonamides are synthetic (nonantibiotic) antimicrobial agents that contain the sulfonamide group. Some sulfonamides are also devoid of antibacterial activity, e.g., the anticonvulsant sultiame. The sulfonylureas and thiazide diuretics are newer drug groups based upon the antibacterial sulfonamides. hence medications containing sulfonamides are prescribed carefully. It is important to make a distinction between sulfa drugs and other sulfur-containing drugs and additives, such as sulfates and sulfites, which are chemically unrelated to the sulfonamide group, and do not cause the same hypersensitivity reactions seen in the sulfonamides. Nowadays, while sulfonamides seldom appear in the prescriptions written by doctors in developed countries, sulfonamides are still common antimicrobial medications in developing countries owing to their low price. Although there has been no specific study to oppose their combined use, there is no practical reason and need for taking these 2 sets of both together.

So, take one only based on clinical judgment with or without urine culture for specific selection with a timely follow-up. In short, please clarify with your prescribing physician.
